Abstract: The invention concerns a system and method enabling the copying of documents. It has specific application to the archiving and retrieval, and the scanning and reproduction, of documents which are or which may be capable of interacting with a computer system or network. Such a document has coded data printed on it allowing it to interact with the computer system or network by use of a sensing device operated by a user. Specifically, the method involves scanning a document which may contain both document information and coded data indicative of an identity of the document, forming a digital image of the document, and detecting, if the document contains said coded data indicative of the identity of the document, the coded data. If the document does contain such coded data, stored data representing the content of the document is accessed, and, depending on the operating instructions, either a copy of the document is printed, together with coded data indicative of an identity of the copy being printed on the copy, or data representing a copy of the document is stored, the stored data including a unique identifier for said copy. The invention can be employed for the printing of documents, the archiving and retrieval of documents, and the scanning and reproduction of documents. In copying documents, it can be used to produce pages of far higher quality than those produced by conventional photocopying means, often irrespective of the physical quality of the page to be copied.

Title: High efficiency engine with variable compression ratio and charge (vcrc engine)
Inventor: COWANS KENNETH W
IPC: F02D15/04
Filed: 2001-11-29
Granted: 2009-09-22
Abstract: An internal combustion engine using variable compression ratio and variable fuel supply to one of two combustion chambers is presented. Varying the compression ratio is accomplished by changing the volume of a single combustion chamber (53) with an auxiliary piston (57) that is biased in an open position by spring (58). This, in combination with lean burning, results in a highly efficient prime mover particularly at the low torque outputs needed in passenger car applications. The relationship of compression ratio and fuel feed is varied with engine speed. Burning occurs in two stages, and this results in a clean exhaust. The invention allows very efficient throttling of two-cycle engines to be realized. A concept for supplying air to a two-cycle engine at very good efficiencies is also presented. The combination of these techniques can result in an engine for automotive use that is half the weight of conventional units with a thermal efficiency of 40 % or more at average engine output.
